Now this is an interesting one tested on two Vario II's. If you add a garbage IMAP email account with random addresses/username and password, using EmailWiz, and once successfully added, immediately soft reset the device (sometimes necessary as we all know), the e-mail account dissapears from the 'Messaging' window.
I think the device still allocates space for it (I deleted my g-mail just to test a mates theory) and even though I can't access this garbage IMAP email account I can't put my g-mail account back on as the device complains saying 'There is insufficient space to create an account', using EmailWiz. Adding a new account through the Messaging windows is to no aviail either, I tap on Tools... New Account and the device just seems to sit there doing nothing. The above seems to trigger this weird behaviour, but my mate has tried this with a valid IMAP email account and it seems to do exactly the same thing.
Just to be complete, heres my ROM n Radio version:
ROM - 126.96.36.199 (06/19/06)
Radio - 1.05.05.00
Protocol - 32.36.7010.04H
Anyone tested this or can validate it? Also, does anyone know where all e-mail accounts are actually stored on the device - need to recover that one e-mail space for gmail!
